PROBLEM TO BE SOLVED: To achieve both the enhancement of spraying properties and the enhancement of safety in a spray unit equipped with a needle-shaped nozzle and an electrostatic sprayer. SOLUTION: The spray unit provided to the electrostatic sprayer (1) is equipped with a container (11) filled with a liquid and the needle-shaped nozzle (21) having a liquid passage, which allows the inside of the container (11) to communicate with the outside, formed therein and applies predetermined voltage to the liquid in the container (11) and internally pressurizes the container (11) to spray the liquid from the tip (21a) of the nozzle (21). A support part (22), which supports the nozzle (21) so as to freely move the same between a protrusion position where the nozzle (21) protrudes from the container (11) and a retraction position where the nozzle (21) is retracted toward the container (11) from the protrusion position, is provided to the spray unit.
